In most instances, residents pay a high premium to live in secure residential estates. Their investment is driven by the need to reside in an environment that ensures unwanted visitors are kept out of the property and any interlopers are apprehended quickly and effectively.
While many estates employ some form of security, often the system is fallible for a number of reasons. “Feedback from Securex exhibitors indicates that two predominant factors come into play: inadequate technology for the application at hand; and the inefficiency or ineffectiveness of the personnel monitoring the security systems,” says Joshua Low, Securex event director at show organiser Specialised Exhibitions Montgomery.
Securex 2015, being held between 12 and 14 May at the Gallagher Convention Centre, will provide visitors with the ideal opportunity to discuss residential estate security issues with experienced specialists who have successfully designed and implemented solutions for this market sector.
While recognising the need for boom gates and other access control technology, along with surveillance and licence plate recognition, perimeter security remains the primary point of contact at residential estates. Dean Sichelschmidt of Arteco says that estate perimeters are often neglected. He adds that it is impossible to deploy sufficient, well-trained security personnel to patrol these perimeters effectively, so the reliance on intelligent perimeter security is vital.
A secure perimeter wall could be a single brick and mortar with electric fencing type structure, or a more modern anti-climb/anti-cut type fence. It may even include a double perimeter boundary with a no-man’s land. Recognising that this will only delay, rather than completely stop the intrusion of any determined criminal, it is imperative to enhance this physical barrier with technologies that are intelligent and offer the security personnel the tools to effectively detect, deter and react to an event.
Arteco offers intelligent video solutions that integrate with access control systems, licence plate recognition systems, electric fencing, lighting, perimeter intruder detection and intruder detection.
Maurice Williamson of Stafix Electric Fence and Security Systems says that to understand the difference between perimeter fencing zoning and sectorisation, one needs to consult the latest legislation and the definitions contained in the SANS 10222-3-2012 Edition 4 regulatory document. In non-professional terms, a zone is simply a portion of fence powered by a single energiser, while sectors are partitions of that zone into smaller sections.
In an effort to reduce costs installers often only install one energiser on a lengthy perimeter fence and then partition this zone into numerous sectors using one of the many different systems available for sectorisation. Generally, the problem with these systems is that a short created on a zone effectively neutralises the whole zone so that when a second or third short occurs, the system cannot detect them. In effect, this means that in many instances the whole of the perimeter security system is compromised and an intruder can, by simply creating a short on one sector, create a diversion and then enter through a breach at another location.
It is therefore advisable to install multiple zones and Williamson suggests using a product like the JVA Perimeter Patrol Management System installed on a fibre optic backbone.
